first steps in collaboration

[Mikus Grinbergs]

Running, on my wired ethernet, an XO with rawhide-xo 20090323.  It 
saw an XO with build 811, and an XO with build 2663.  Was able to 
set up a working Chat session among all three XOs (on ethernet).

[At this time I was not able to set up collaboration in Write.]
